That's probably not a bad idea, although I doubt it will make much of a difference. But since you're redesigning the whole thing, might as well do it.

It looks like you would want an even airflow through the whole PSU. The main heat-generating components are using the sides of the housing as a heat sink. I'm guessing the fan is mostly so the air inside the housing doesn't get too warm, not to cool individual components.

Where is the original air exhaust? If it's near the bottom of the picture, that would confirm my theory. In that case, I would keep the fan placement as close to original as possible (i.e. the blue square).

Double-check my first PC build (de.pcpartpicker.com)

My 5 year old notebook is starting to show it's age, so I want to finally build a "real" PC. I rarely play games, so this is probably overkill - But I don't want my PC to be what's stopping me. I also expect it to last a while.

I chose all AMD because I'm running linux, and AMD seems to still be the best choice for that.

I found a couple similar posts on which I based this list, so most of the parts are probably fine. I'm unsure about the cooler: How much headroom should I leave? This one is rated just 10W higher than the CPU TDP, so it might be cutting it too close.

Do you expect every meme to be meticulously handcrafted? It's a stupid joke, not a work of art.

IIRC, this is actually done at some point in the books.

You can host a Firefox sync server yourself. You could run that on something like a Raspberry Pi in your local network. If you need remote access, use something like cloudflare tunnels (although I guess that's something else to be paranoid about).

Windows is clearly superior. If you've had enough of the settings app, you can just switch to the control center!

I just found out that the Getty museum released a lot of artwork into the open domain, including quite a few stereographs. These are meant to be viewed with a stereoscope, but I’ve found they work amazingly well in crossview.

What did you expect? We're talking about one guy who might have lived over 2000 years ago. You're not going to find his birth certificate and social security number.

The best anyone can do is assign a probability to his existence. And reading the article you yourself linked to, that probability seems to be pretty high.

Sorry dass ich nichts hilfreicherws beizutragen habe, aber der Janosch passt hier einfach zu gut:

Herr Janosch, schwere Entscheidungen, wie trifft man die? "Man schreibt die Alternativen tabellarisch auf einen Zettel. Anschließend legt man den Zettel nieder und wirft einen Löffel auf den Zettel. Dann geht man weg und lässt den Löffel das regeln. Sein Problem."

That study states that brain damage can cause more conservative views, but the reverse isn't true. Not everyone with conservative views has brain damage.

I built my 3D printer a couple of months ago, but I can't get it to print sharp corners. The corners in the picture should be 90°, without any fillets:

During this test print, I played with multiple parameters: speed, temperature, acceleration, junction deviation, linear advance. All of these were also individually tuned previously. Nothing seems to make a difference.

Could this be a issue with the construction of my printer? I'm beginning to think my hotend isn't rigid enough, but then I would at least expect better results at low speeds.

Edit: the printer is a CoreXY of my own design running Marlin 2.1.2.1. The Slicer is PrusaSlicer with most settings left as default (but increased speeds)

It's called HDR (High Dynamic Range) photography. Your phone is taking three pictures: one at a medium exposure, one at a bit higher exposure and one at a bit lower exposure.

The higher exposed picture will have a blown-out sky, but more detail in the darker area, while the lower-exposed one will have a correctly exposed sky with the darker areas underexposed.

These pictures are then combined by taking the correctly exposed areas of each picture, i.e. the sky from the low-exposure picture and the shadows from the high-exposure one, giving you a single picture without over- or underexposed areas.

I don't know about OpenCamera, but you should be able to select the size of the exposure bracket, meaning how much higher or lower the different pictures are exposed.

These brakes are single-pivot side-pull caliper brakes. They can work well, but only if they are well made - I personally never had much luck with Weinmann brakes.

For the rear brake, pretty much the only thing you can try is replacing the brake pads. The front ones don't look very worn, but the rubber gets hard with age and loses its effectiveness.

The front brake looks broken beyond repair. The part I circeled red should be attached to the green part, but the connecting part seems to have broken off. You might be able to find a replacement, but I would recommend replacing the whole brake for a better one.
